Topic: Pocketing Problem (Read 1752 times)

I am very new to Mach and have encountered a problem that is probably an easy fix for someone with experience. When I am doing rectangular pocketing the end mill will take a circular detour in two places that extend outside of the rectangle that I am pocketing. This occurs at two adjacent corners. I am designing in Dolphin CADCAM and posting the g code to Mach. What am I doing wrong?I'm sure there must be a simple answer, but I have failed to uncover it in my searches of the forum. The animation looks fine in Dolphin, but the "extra" circles show up in the Mach toolpath. Please help. thanks...

Sounds like you may need to change the IJ mode, its on the General Config page. You can also do it via code and your G Code should really have it in it so that it works without having to manually change. The G Codes are G90.1 for Absolute IJK mode and G91.1 for Incremental IJK modeHood
